Given numbers are 456,894,856,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 456,894,856,663 is 1606671768.
Find LCM of 456,894,856,663 with Prime Factorization
| 2 | 456, 894, 856, 663 |
| 2 | 228, 447, 428, 663 |
| 2 | 114, 447, 214, 663 |
| 3 | 57, 447, 107, 663 |
| 19, 149, 107, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 19 x 149 x 107 x 221 = 1606671768
Therefore, the lowest common multiple of 456,894,856,663 is 1606671768.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
456 x 894 x 856 x 663 = 231360734592
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
894 : 1, 2, 3, 6, 149, 298, 447, 894
856 : 1, 2, 4, 8, 107, 214, 428, 856
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,894,856,663, is 1.
Now, the common factors can be found like this.
456:2x 2x 2x 3x 19
894:2x 3x 149
856:2x 2x 2x 107
663:3x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 231360734592/(1x144)
LCM = 231360734592/144
LCM = 1606671768
Thus, we can understand that the LCM of 456,894,856,663 is 1606671768.
